韓国の株式市場において、時価総額が1兆ウォンを超える上場企業の数が今年初めて400社を超えた。これは中東情勢の緊張が高まる前の株価回復を受けたもので、KOSPIは過去最高値を記録した。
韓国取引所（KRX）のデータによると、優先株を含む時価総額が1兆ウォン（6億7970万米ドル）を超える上場企業は、5月1日水曜日の時点で405社に達した。その内訳は、KOSPI市場が267社、ハイテク企業中心のKOSDAQ市場が137社、KONEX市場が1社となっている。
この数字は、米国とイスラエルがイランへの攻撃を開始する直前の2月27日時点の377社から大幅に増加した。紛争開始後、市場は一時12％近く急落したが、決算シーズンを控えた人工知能（AI）ブームにより回復に転じた。
KOSPI指数は水曜日に6690.9ポイントの過去最高値で取引を終えた。この回復は、中東紛争勃発前の低水準から劇的な転換を果たしたことを示している。
